The builds 160-161

15.0.161 (12/3/2010)

1. Fixed: DLNA Server, PS3 video "convert when necessary" add xvid as natively playable media.
2. Fixed: Possible rare crash when DLNA devices left the network.
3. SDK: Added 'AccessKey' to MCWS/v1/Alive response.
4. Changed: Reverted to using a simple reader instead of a more sophisticated buffering reader for Library Server audio playback (new reader to return later).

15.0.160 (12/1/2010)

1. Fixed: On some CD/DVD burners, enabling 'test mode' could still result in the disc getting written to.
2. Fixed: In CD/DVD burning, the order of transmitting certain commands to the burner was changed which seems to improve reliability on certain burners, namely Samsung.
3. Changed: DLNA Server, more tweaking of video conversion autodetect, especially for the PS3.
4. Changed: Reworked how paths are stored in options so that they are user account relative when possible.
5. Changed: Restoring a library with settings from a different OS or different user account will work better.
6. Faster: Improved core browsing system of database for lower memory usage and better performance (helps program navigation performance and Gizmo performance).
7. Faster: Servers that power DLNA, WebPlay, Gizmo, etc. will use gzip compression for clients that support it.
8. Fixed: DLNA server, mkv files with h264 video will now play properly on the WDTV (and others that support this format).
9. Fixed: When resampling, startup silence for hardware synchronization durations would not be adjusted properly.
10. Fixed: WAV playback was not working over Library Server.
11. Changed: Added smartlist location specifier 'r' to show removed files (i.e. ~d=r).
12. Changed: Added smartlist location specifier 'g' to show television guide files (i.e. ~d=g).
13. SDK: When making an MPL request from MCWS, a list of desired fields can be specified (makes Gizmo file requests much faster).
14. SDK: MCWS file requests can optionally suppress returning filenames that point to local files while still getting URL filenames (makes Gizmo faster).
15. Changed: DLNA playback of video files on the XBox with conversion enabled now uses a higher 720x480 resolution.
